The DCOM Server Process Launcher (DCOMLaunch) service launches COM and DCOM servers in response to object activation requests. This service is installed by default and its startup type is Automatic. When the DCOM Server Process Launcher service is started in its default configuration, it logs on by using the Local System account.
If the DCOM Server Process Launcher service stops, remote procedure calls and DCOM requests on the local computer do not function properly. In particular, the Windows Firewall service fails if this service stops. This service is required and cannot be stopped from the Services console. If this service stops, the computer restarts.
The Remote Procedure Call (RPC) service is dependent upon the DCOM Server Process Launcher service.
